Tech‑Based Brain Boosts Before Surgery: A Quick Look
Sunday, June 7, 2026
Researchers are investigating whether brief computer or phone training before surgery can reduce the incidence of delirium—a common, costly complication—especially in older adults.
How the Study Was Conducted
- Search Scope: Reviewed over 600 medical database hits for trials that tested digital cognitive exercises around the time of surgery.
- Eligibility: Included English or French papers focused on participants aged 60 and above.
- Final Selection: Six studies met the criteria.
Key Findings
| Study | Surgical Context | Cognitive Domain Targeted | Training Duration | Outcome |
|---|---|---|---|---|
| 1 | Orthopedic | Attention & memory | 15 min pre‑op | Reduced delirium |
| 2 | Cardiac | Executive function | 30 min pre‑op | No significant effect |
| 3 | Neurosurgery | Working memory | 20 min pre‑op | Modest benefit |
| 4 | General surgery | Visuospatial | 10 min pre‑op | No clear advantage |
| 5 | Orthopedic | Memory | 15 min pre‑op | Mixed results |
| 6 | Cardiac | Attention | 25 min pre‑op | No significant effect |
- Mixed Results: A couple of studies indicated a potential benefit, while others found no clear advantage.
- Strict Inclusion Criteria: May have limited the generalizability of benefits.
What This Means for Future Care
- Field is Emerging: More research is needed to determine optimal dosing, ease of implementation, and broader applicability.
- Potential Tool: Digital brain exercises could become a low‑cost adjunct to reduce delirium if future studies confirm efficacy.
